Physics H133: Problem Set #2

Here are some hints, suggestions, and comments on the problem set.

Two-Minute Problems

Remember to give a good explanation, no longer than two sentences.

  1. Q2B.8: Is a deep voice dominated by long or short wavelengths? How about a high voice? What does the wavelength have to do with how well the sound carries around a corner?
  2. Q2S.4: You would not hear music where the sound waves from the two speakers are exactly out of phase. Where does this happen if you've reversed the wires? Would the waves be out of phase everywhere in the room?

Chapter Q2 Problems

Your comments and suggestions are appreciated.
